Yumurta allerjisi olan çocuklarda kızamık-kızamıkçık-kabakulak aşılaması sonrası reaksiyon durumunun değerlendirilmesi.

Objective: Although direct administration of the measles -mumps -rubella (MMR) vaccine which contains egg protein is recommended to children with egg allergy, physicians often have reservations, this situation leads to problems in physicians and families. In this study, we aimed to evaluate the frequency of reaction after the MMR vaccine in patients who were monitored for egg allergy in our clinic. Methods: MMR vaccination records were examined between January 2019 and January 2020 of patients diagnosed with egg allergy in our clinic. Demographic and clinical characteristics, laboratory findings were evaluated in patients vaccinated with MMR Results: The average age was 6.1±2.7 months, and 62.5% (n=50) of the cases were male. According to their diagnostic distribution, the patients had atopic dermatitis (n=55; 68.8%), urticaria (n=15; 18.8%), reactive airway disease (n=20; 25%), proctocolitis (n=13; 16.3%) and anaphylaxis (n=12; 15%). A whole dose of vaccine was administered to all cases. Flushing and crying was observed in one patient 30 minutes after vaccination, while her complaints resolved 1hour after antihistamine. No problems were observed in the follow-up of other patients. There was no severe side effect in any of the cases. Conclusion: No serious reactions have been observed in patients with egg allergy after the MMR vaccine. We believe that the MMR vaccine can be safely administered in patients with egg allergy in vaccinated centers, as immunization and delivery time are important. However, appropriate conditions can be intervened in possible reactions and patients should be kept under observation for the appropriate period after vaccination.
